Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453706, here are decompositions:

7 + 31453699 = 31453706
199 + 31453507 = 31453706
223 + 31453483 = 31453706
313 + 31453393 = 31453706
373 + 31453333 = 31453706
439 + 31453267 = 31453706
457 + 31453249 = 31453706
499 + 31453207 = 31453706

Showing the first eight; more decompositions exist.
